Gallery: FA Cup training
As injuries begin to take their toll ahead of Saturday's FA Cup fourth round tie with Tottenham Hotspur, Sir Alex has called in the cavalry, with several promising youngsters being drafted into the first-team squad.
As our gallery shows (click on the main image), there were plenty of new faces at training on Friday morning, with young defenders James Chester, Fabio, and Richard Eckersley all joining in the session.
Rio Ferdinand and Wes Brown were also involved as they continue their recovery from back and ankle problems respectively. The pair are expected to return to action for Everton's visit to Old Trafford on Monday 2 February.
